Photo-polymerizable, low shrinking modular construction kit with high efficiency based on vinylcyclopropanes

Studies of Photo-emission and Field Emission in an Rf Photo-injector with a High Quantum Efficiency Photo-cathode

An 18 MeV electron photo-injector facility was constructed at Fermilab in collaboration with UCLA, INFNMilano, University of Rochester, and DESY. The photoinjector is now being operated in partnership with the Northern Illinois Center for Accelerator and Detector Development. The facility consists of an RF gun [1, 2] with a cesium telluride (Cs2Te) photo-cathode [3] excited by a pulsed ultra-vi...

A High Torque Density Axial Flux SRM with Modular Stator

A novel structure of switched reluctance motors (SRMs) is proposed. The proposed structure uses the benefits of the axial flux path, short flux path, segmental rotor, and flux reversal free stator motors all together to improve the torque density of the SRMs. The main geometrical, electrical and physical specifications are presented. In addition, some features of the proposed structure are comp...

A modular framework for randomness extraction based on Trevisan's construction

Informally, an extractor delivers perfect randomness from a source that may be far away from the uniform distribution, yet contains some randomness. This task is a crucial ingredient of any attempt to produce perfectly random numbers—required, for instance, by cryptographic protocols, numerical simulations, or randomised computations. Trevisan’s extractor raised considerable theoretical interes...

High Efficiency Volume Diffractive Elements in Photo-Thermo-Refractive Glass

A Photo-based Augmented Reality System with Low Computational Complexity

In this report, we propose an augmented reality (AR) system using photo images. Based on the position and orientation of the user’s camera, the system selects the most appropriate image of an object from a set of photos taken at various angles and “pastes” it into the camera image at an appropriate location and scale. Since the technique requires no 3D model creation or 3DCG rendering during th...
